You need to fill the hole... I would adhere on the other side.. thin copper sheet cut to size using thermal adhesive for all that "Holes" where the Chips Soar Sky High with no thermal sensor to FOOL YOU PEOPLE!!
Once you adhere the copper & add the Thermagon or that material you found in an old Printer? that could work possibly... You'll notice a Huge reduction in VRM temperature & the Whole PCB will cool down by 20-40C after you do this... That's 40 degrees celsius.
My 390X outperforms VEGA on Double Precision which is awesome! haha I love the 390X but the only thing I hate about it is... Lack of HDMI 4k 60Hz... 30Hz 4k is Ultra-Lame. So I need to get the Startech Displayport to HDMI adapter it's shorty stubby adapter allows 4k 60Hz on 390X.
It looks like your PCIe is stuck in PCIe 1.0 it appears on the VEGA & 290X stuck in PCIe 1.1 .... I would revisit the CHIPSET DRIVER & Checkout Anything PCIe GPU Related Settings in the Motherboard BIOS.
The 290X & VEGA if on a PCIe 2.0 motherboard should look at 6,500 MB/s READ/WRITE ... Half is 3,250 MB/s READ/WRITE this is all PCIe Bus here and that's PCIe 1.1 .... Half Of That is PCIe 1.0 Revision 1 ancient & slower than ever...
Good luck... Retest until you get those Read/ Writes Up & Scores will be a lot better as a result, especially at high resolution like 3840x2160 +.
It's not that. I'm aware of the 290x being x4, but its just a slave card for 2nd monitor, supposed to be gimped.
The vega is on a x16 gen 3
